To all whom concern.' l

Be it'known that I, JESSE A. B. SMITH, a citizen of the,lU11ited`States, residing in Stamford, in the lcounty of Fairfield and State ofConnecticut, have invented certain new and useful Improvements inTypewriting Machines, of which the `following is a specication. f

rllhis invention relates to improvements in fan-fold or continuousbilling typewriting machines, such as disclosed in the Werner & Smithpatent, dated March 16, 1915, No. 1,132,055. 'llhe plies of continuousworksheets or fan-folded webs are threaded between carbon-holding bladesand are thus interleaved with the carbon-sheets which areY fastened tothe blades. 'llhevleading end of the web or pack fed yforwardly andunderneath an around the platen to be typed upon.

Sometimes it becomes desirable. for the same typist to work with twodilierent lengths and kinds of work-sheet units. An object of theinvention is to provide im proved means whereby two separate packs ofcontinuous work-sheets or dissimilar fanfolded webs may be usedsuccessively or alternately.

To this and other ends, there is provided means whereby two fan-foldwebs or separate packs of sheets may be carried simultaneously in amachine, and either pack used at will exclusively of the other. lncarrying out the invention, the packs or webs-are superposed, and eachpack is provided with its own set' oi' carbon-sheets and bladestherefor.

Each pack is retained upon the carboncarrier, to move idly therewithwhen the other pack is being typed line by line. When the upper packisto be t ped, the forward end of the lower pack is rst withdrawn from theplaten and folded back, and its end is tucked back in a pocket which is.prepared to receive it, this pocket bein far enough back so that thefold of the ower pack will not rest at 'such a point as to foul thepaper-guiding devices on the typewriter All carriage, when thecarbon-carrier is pulled.

forward. This pocket underlies the top pack or web, so yt at, while thelower web 1s folded back into said pocket, the top pack may be carriedaround the platen and typed, regardless of the lower pack, which simplyforward and back idly with the motion of Y the carbon-carrier. .f

In order to secure this result, the carbony blades (lpf which theremaybe six or more,

althoug only two or three Aare illustrated) yof the superposed pack aremounted above said pocket. The position of the latter may the lowerk setof blades. The poc et is made spacious, and the upper set of blades may`rest either directly over the lower set of the lower pack folded backinto the pocket.

A displaceable platen 3 may be mounted as usual in a swing-frame 4 tooscllate about a transverse shaft 5 secured at its ends in a carriage 6,and may bel rotated by means of either a platen knob 7 (attached to aplaten-knob shaft 8, to which is attached a spur gear 9, which rotates asimilar spur gear 10, mounted on a platen shaft 11, through av spurpinion; 12 mounted on the transverse shaft 5), or ordinary line-spacemechanism 13. Feed-rolls 14I and 15 may be used to co-operate with a,rear papertable 16 in feedin work-sheets underneath `and around the paten 3. A front paperbe between the blades of the up er,set and YSupported .by means of brackets 22 fastened'to the rear of the carriage6 may be a usual work-supporting frame 23, a rear end membery 24 ofwhich may support, by means of brackets 25, a ywork support 26, .whichmay be' `fitted with paper-gages 27. Usual side members 28 of thework-presenting,

frame 23 are'tted with rails 29 yon which maybe supported, by means ofrollers 30, a carbon-carrier3l. l.

Mounted upon a base 32 ofthe carboncarrier 311is an operating handle32a.

Upon the 'carboni-carrier 31 is a set 37 of carbon-holding blades 38, ofwhich there maybe six or Imore, although only two are illustrated.kThese are mounted individually upon Asuplports 39, one on each side ofthe base 32. paclg 40 of continuous worksheets 40a is brought over thework-support 26 and may be threaded through the car-bom".

holding blades 38, to ble-interleaved with carbon-sheets 40`b'which areattached thereto.

.These work-sheets in pack 4() may be carried forward and down aroundthe v carbon-blades 46, which carry the 'interleaved carbons 49b forthis pack. These carbon-blades 46, of which -there may be six or more(onl Vtwo being shown), are carried upon ane evated'support 47 mounted un the carbon-carrier 31. As shown at Figure 1, the forward end of thetop pack is folded back at 49, so that by reason of its weight thefolded-back portion rests u n the pack and upon the carbon-blades,Wlhoere it travels idly back and forth with the carbon-carrier duringthe typing of the lower pack 40.

. 'Wheneverv desired, the lower pack may be withdrawn from the platenand its for- Wardportion 'folded back, as at 40, Figure 2,preparatory tounfolding the top pack 49 and passing it forward to and around theplaten 3, as at Figure2.

For the reception of the folded-back part of the under pack, there isprovided a pocket 'X3 Y, above the set Vof carbonblades 37 land belowthe set of carbonblades 45, the spaces between the brackets.

.4 6 are 'mounted at a great elevation with respect to the`carbon-blades 38. ,Y The car- .bon-blades 46 with their support may beplaced either directly above the set of carbon-blades 37, or a little inrear thereof, as shown at Figure 2, the latter being the preferred form,since, .by setting-this upper set considerably back of the lower set,the

space between the sets is much enlar d in a horizontal direction, tofacilitate t e introduction of the end of the pack of sheets thereinto.

lVhenever desi-red, the upper pack 49 may be withdrawn from the platenand folded.

back, asat Figure 1, andthe lowerpack again carried'around'the platenfor typing thereon. 'y

Thusby a compact and simple device provision 'is made whereby t-he packsma be used in alternation as required, an 'v as many forms may be typedand torn olf from each pack as desired, while the other k is carriedidly to and fro-by the carmcarrier. 1

Variations may be resorted to within the scope of the invention, andportions of the improvements may be used without others.
